The 28mm LightLeak Lens from Polar Pro is a fixed focus lens with an f/11 aperture for producing film-like images on Canon RF/Sony E mirrorless cameras while also giving you additional control of its creative effects. The lens gives your photos a grainy, nostalgic look without vignetting, ensuring an even exposure across your frame. When you want to add an additional layer of vintage feel, engage the adjustable light leak ring to let light pass into the back of your lens to create an even dreamier look. The collar can be rotated when engaged to alter how and where the light passes into your image, making each photo unique.
